1 Claim.

The present invention relates to new and useful improvements in motor torpedo boats and has for its primary object to provide a relatively small vessel of this character adapted to be easily and quickly maneuvered and of relatively shallow draft to enable the boat to travel over mine fields and capable of mounting a pair of torpedo tubes below deck in the forward portion thereof and providing hinged sections in the sides of the boat immediately adjacent the bow and adapted to be swung into an open position to permit discharging of the torpedoes from the bow of the boat.

Th invention has for its further object to also provide means for carrying a plurality of depth charges in the stern of the boat.

A still further object is to provide a boat of this character of simple and practical construction, which is efficient for use in heavy seas as well as in sheltered waters, which is relatively inexpensive to manufacture and maintain in use and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout and in which- Figure l is a side elevational view.

Figure 2 is a front elevational view.

Figure 3 is a vertical longitudinal sectional view.

Figure 4 is a top plan view.

Figure 5 is a longitudinal horizontal sectional view taken substantially on a line 5-5 of Figure 1.

Figur 6 is an enlarged fragmentary sectional view of the bow end of the boat similar to Figure 5 and showing one of the hinged sections for releasing the torpedo in an open position.

Figure 7 is a rear elevational view, and

Figure 8 is a transverse sectional view taken substantially on a line 8-8 of Figure 3.

Referring now to the drawings in detail, the numeral 5 designates the hull of the boat generally having a single V bottom 6 at the bow portion and a double V bottom 1 and 8 in the stern portion and extending forwardly to a point forwardly of the amidship section of the boat.

A deck 9 covers the top of the boat having a deck house or cabin l0 formed therein provided with front windows II and side windows I2.

The engine or power plant is designated generally at I3 for driving twin propellers l4 and I5 having their propeller shafts extending in the center line of the respective double keels 1 and 8.

A decking Hi extends from the bow of the boat to a point beyond the cabin l0 and terminating at its rear end in a tranverse bulkhead ll, the deck [6 and bulkhead l'l forming a forward torpedo tube compartment i8 having a pair of torpedo tubes I9 and 20 mounted therein with the rear ends of the tubes projecting through the bulkhead ii. Each side of the hull of the boat immediately adjacent the bow thereof is provided with an opening 2| and 22, the opening 2| being closed by a hinged hull section 23 and the opening 22 being closed by a hinged hull section 24, the openings being formed in the sides of the boat above the water line thereof. To the inside of the sections 23 and 24 are secured brackets 25 and 26, respectively, pivoted on a pin 21 secured to the inside of the bow of the boat as shown to advantag in Figure 6 of the drawings. To the inside of each of the sections 23 and 24, adjacent their rear ends, are pivotally secured sectional links 28 and 29, respectively, one end of each of the link units being pivotally connected to a post 30. The sections of the links 28 are pivoted together, as at 3|, and the sections of the links 29 are pivotally connected to each other, as at 32. Also pivotally connected to the pivot 3| is a link 33 extending rearwardly with its rear end pivoted, as at 34, to a bell crank lever 35 pivoted intermediate its ends, as at 36, to the inner front edge of the tube [9. To the rear end of the link 35 is pivotally attached an operating lever 31 extending rearwardly between the tubes for actuation of the section 23 in any suitable manner for opening and closing said section to permit the torpedo 38 to be discharged through the opening 2| from the tube IS in a manner as will be apparent.

Likewise attached to the pivot 32 of the link section 29 is a link 38 attached to a bell crank lever 40 and also having a manipulating rod 4| attached thereto for opening and closing the section 24 of the hull in a like manner.

The stern of the boat is provided with a flat transverse section 42 having a, plurality of tubes 43 fitted therein and extending forwardly of the stem, the tubes 43 being adapted to hold a depth charge to be discharged from the stern of the boat.

Compressed air from a suitable source of supply is fed to the tubes 43 by a hose 44 extending through a loading cap 45 for discharging the depth charges.

The deck 9 is provided with latch covers 46 providing access to the interior of the boat.

It is believed the details of construction and manner of use of the device will be readily understood from the foregoing without further detailed explanation.

Having thus described the invention what I claim is:

A torpedo boat comprising a hull having torpedo dischargecopenings in its sides above the water line and immediately adjacent the bow of the boat, a pair of doors for said openings mounted for swinging movement into the hull into an open position, a sectional link pivoted at one end to each door, a fixed pivot for the other end of each link, each of said links including a pair of sections pivoted to each other on an intermediate pivot pin, an arm also pivoted to the sections at said intermediate pivot pin, a bellcrank lever pivotally mounted in the hull and connected at one end to the arm, and a manually operable rod connected to the other end of said bellcrank lever and adapted upon a" forward or backward movement of the rod to actuatethe door.
